l STATES l PATENT OFFICE.

IMPROVEM ENT IN POTATAO-PLOWS.

Specification forming part of Letters Patent No. 106,702, dated August 23, 1870.

To all whom it may concern Be it known that I, AUGUSTUS LEONARD, of Newells Run, in the county of Washington and State of Ohio, have invented a new and useful Potato-Plow; and 1 do hereby declare that the following is a full 'and exact description ot' the same, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon.

This invention has for its object the production of a plow,lespecially designed for use in the cultivation of potatoes, the shovels of which may be adjusted laterally by means ofthe handies; and it consists iu certain details of construction, whieh will be fully described hereinafter.

In the drawings, Figure l represents a side elevation of my improved plow, and Fig. 2 a plan view ofthe same. 4

To enable others skilled in the art to make and use my invention, I will now proceed to describe fullyits construction and operation.

A represents the center beam, and A A the Side beams, of my improved machine. These beams are rigidly united at their front ends, andare suitably curved and provided with shovels a a a at their rear ends, as shown. The center beam, it will be observed, is longer than the side beams. They are constructed preferably of metal, having sufficient elasticity to permit the side beams to spring in toward the center beam when such action is necessary.

B representsaeonnecting-beam, which is rigidly attached to the center beam and extends on each side through a suitable oritce in the side beams, and is provided with a pin or stop at each end. It is provided also with shoulders b b, as shown, by mfans of which the iuward lateral movement ot' the side beams is limited.`

c c represent arms rigidly attached to the rear en d ofthe center beam, as shown.

d d represent handles, which are secured to thearms cc by meausofa bolt or pin, as shown. The front ends ot' the handles rest in staples attached to the inner sides ot the side beams, A A.

The operation will be easily understood. The machine is used in the ordinary manner. The location of the center shovel iu rear ot' the side shovels is important, inasmuch as the ridge formed by the latter is thrown down, and the ground is'left nearly level.

The general construction is extremely simple and not liable to get out of order. The diso tance between the shovels is easily regulated by the handles.

I do not claim the constructing ot' a plow with shovels adjustable by means of' the handles, for this I know is not new; but,

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The plo7 described, consisting of the beams A A A', rigidly secured at the front ends, connecting-beam B, arms c c', and handles el d', when all the parts are constructed and arranged as described, for the purpose set forth.

This specilication signed and witnessed this 16th day of April, 1870.
